of Philip IV at Fraga 1644 Philip IV at Fraga was painted in 1644 during his Argonese campaign to take back the city of Lerida from the French. It was painted by the Diego Rodríguez de Silva y Velázquez who was Philip’s court painter who accompanied him to Fraga. Velázquez used oil paint on canvass to create an impressionist portrait depicting Philip IV in his military uniform holding his sword and baton of command. It can now be located in The Frick Collection in New York. Philip IV ascended

Investigating the effect of temperature on the action of a protease enzyme on exposed developed film Plan Aim: The aim of the experiment is to find out what effect temperature has on the action of a protease enzyme on exposed developed film. Enzymes are biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature "Y pH
